REFRIGERATO R.

SPECIFICATION forming part of Letters Patent No. 467,225, dated J' anuary 19, 1892.

l Application iiled April 21, 1891. Serial No. 382.813- (No model.)

To all whom it may concern:

Be it known that we, LABAN J. EVEREST and HENRY C. BETTERMAN, citizens of the United States, residing at Omaha, inv the county of Douglas,.State of Nebraska, have invented certain new and useful Improvements in Refrigerators, of which the following is a specifi.- cation, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in refrigerators; and it has for its objects, among others, to provide an improved device of this character wherein provision is made for the free passage of the cold air from the ice-chamber directly down to the storing-chamber, and thus force the warm air up each side of the end of the icechamber and out through openings provided in the end of the chamber, making afull and free circulation.

In our improved refrigerator the ice-chamber is made removable, and the bottom is formed-of separated convex bars, which are alternately arranged with concave bars removably supported within the refrigerator. The lower or concave bars communicate with a drip-trough having a discharge-pipe. An air-space is provided at each end of the icechamber.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically defined by the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon,form a part A of this specification, and in which- Figure 1 is a vertical cross-section through a refrigerator embodying our invention. Fig. 2 is a detail, partly in section and partly in side elevation, with parts broken away, the section being taken at right angles to the section of Fig. 1 and showinga slightly-modified form of ice-chamber. Fig. 3 is a perspective detail showing a modified form of bar.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates the case or box, preferably of wood, lined with some suitable non-conducting material, as asbestus, preferably of two layels, as seen at B, and an interior lining O of zinc, with an air-space A between the zinc and asbestus, as shown in Fig. 1. It may be provided with any desired numberand style of doors.

` Vithin the case, preferably at one end, is affixed a dripftrongh D, which may be supported therein in any suitable manner, and is provided with a discharge-pipe D', which may extend through the bottom or side or end of the case, as may be found most desirable. Upon aline slightly above the upper edge of this drip-trough we arrange suitable supports a, which maybe affixed to the inner walls of the case in any desired way and designed to support the removable drip-bars E, which are several in number, which number may be varied according to the size of the box or the number of inversely-arranged bars in the ice-chamber. These bars are all secured to end supports b, and are provided at the ends over the dri p-trough with dischargeopenings c, as seen in Figs. 1 and 2. The bars are substantially semicircular in cross-section, as seen in Fig. 2, and are arranged with their concave face uppermost, as seen in Fig.

2. The bars are supported by means of their end supports upon the supports a. These bars are readily removable for the purpose of cleaning or for other reasons.

The ice-chamberF is made of heavy galvanized iron preferably,whieh is of sufficient thickness as to be proof against punctures by the ice-pick in breaking the ice, and it is provided at its upper edge with a surrounding horizontal flange d, which at its outer edge is turned down, as seen at c, to embrace the outer walls of the case or box, as seen in Fig. l, to close the upper end of the box or case. The bottom of the ice chamber is formed of separated bars G, which are substantially semicircular in cross -section, as seen in Fig. 2, and are arranged with their convex face uppermost. These bars are suitably secured to the end walls ofthe ice-chamber, and are so arranged as to alternate with the bars E-that is, so that the bars cover the spaces between the lower sets of bars-as will be readily seen from Fig. 2, so that the drip from the upper bars will fall into the lower bars, and from thence conducted into roo the drip-trongh and through its dischargeplpc away into the sewer or other place of deposit. The upperbars are supported at a distance from t-he lower bars, so as to provide space for free circulation of the air therebetween, as will be seen from Fig. 2.

The end Walls of the ice-chamber are provided with one or more openings f, as seen in Fig. l, through which the hot air rising from the storage-chamber passes and forces the cold air downward, as indicated by the arrows in Fig. l.

Vithin the ice-chamber we arrange the de fleeting-plates H, which are connected with the end walls of the ice-chamber above the openings therein and extend downward for a sn iiicient distance and their lower edges preferably turned inward, as seen at g in Fig. l, to deflect the air toward the center of the icechamber. The passage ofthe air and the full circulation will be understood from the arrows in Fig. l.

The ice-chamber is provided with a removable cover I, and the chamber itself is removable bodily fromwthe box for the purpose of cleaning the parts.

The bars of the rack or bottom of the icechamber may sometimes be constructed in the manner shown in Fig. 8, the operation being the same; but the brace h greatly strengthens the same, the said bra-ce havingits edges turned at a right angle with the body thereof and clamped between the turned-over edges of the bar, as shown clearly in Fig. The

upper contour of the bar is the same in both instances.

The ends of the icc-chamber are extended, as seen at j, so that when in place the extended portions form, with the inner end walls of the box or case, air-spaces 7.1,as seen 4o in Fig. l.

lVe sometimes provide the sides of the ice-chamber with interior plates L and slot the side walls, as seen at 711to form air-passages, as seen in Fig. 2; butthis may be omitted without materially atecting the successtul operation of the other parts.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages. d
